AJ,
Sizes are over the board. A Euphasiid or nymph are rather small compared too a polychaete worm or a stimulator, but all will catch searun cutthroat.
How do you want to fish, subsurface or on top, saltwater or fresh?
More info will help Swimmy answer your questions.

Lots of different subsurface options. The time of the year you are fishing will play a part in your pattern selection. You can tie most of these on size 6 or 8. Hooks.
Here are a few to consider.
Muddler
Sculpin
Polychaete worm
Small herring and Sandlance patterns
Johnson Beach Fly
Searun Bugger
Clousers - Olive /white, olive / yellow, tan / white
Chum Fry patterns
Euphasiid and Ampipod patterns

If you search the tying and saltwater forums you'll come up with a lot of good saltwater searun fishing info and patterns to try.
Good luck and have fun,
SF
